Hotel is in a great location - very close to Trevi fountain/Spanish Steps/metro etc.
The rooms were clean and tidy and had a security box. Our rooms faced onto the road and so were quite noisy. You could also hear people in other rooms, albeit not loudly.
Our shower head was slightly loose so the water trickled out.
For the price and location you could not do better.

Clean basic Hotel. Ideally positioned for Trevi Fountain, Spanish Steps and other places of interest. We would stay there again.

Great location. Clean. Breakfast mediocre.

The location is really good - about 5 minutes to the Trevi fountain and lots of nice restaurants. There is no need to book a tourist bus tour because all the major sights are in walking distance (Colosseum, Vatican 15-20 minutes)

If you book this hotel make sure that you ask for a quiet room. A friend of mine arrived before us and got a really noisy room. When we checked in we requested a quiet room. We were lucky that we got one because they told us that we should have requested a quiet room when we booked. The mattress in our bed was really, really terrible, so if you have back problems that might not be the right place for you.

Not all rooms have A/C, so make sure you request a room with A/C when you book.

The staff were very polite and helpful. The price in September was really high (170 Eur/night), but they occasionally have weekend offers. You have to email them to get these offers. We also noticed that the Domus Julia (a B&B which belongs to the hotel) is a bit cheaper and it's right next door. It's worth sending an email to ask for the price of both the hotel and the B&B. We received replies to our emails withing 12 hours and with the special offer paid about 120Eur/night.
